gpgcheck=1
gpgkey=https://packages.fluentbit.io/fluentbit.key

note: we encourage you always enable the gpgcheck for security reasons. All our packages are signed.

Once your repository is configured, run the following command to install it:

$ yum install td-agent-bit

$ service td-agent-bit start
